WINDOW-SASH-OPERATING MECHANISM.

SPECIFICATION formingpart of Letters Patent No. 719,221, dated January 27, 1903.

Application filed March 28, 1902. Serial No. 100,447- (No model.)

To all who-in it may concern:

Beit known that 1, PAUL A. HOUGHTALING, a citizen of the United States, and a resident of Riverton, New Jersey, have invented certain Improvements in Window-Sash-Operating Mechanism, of which the following is a terbalanced by means of a weight connected through the medium of a lever or levers. This object I attain as hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is an elevation of a car-window, showing my improved sash-operating device attached thereto. Fig. 2 is an enlarged vertical sectional view of a portion of a windowsa-sh, taken on the line 2 2, Fig. 1. Fig. 3 is an elevation of the upper portion of a sash, showing my improved device as applied to the top instead of the bottom of the window. Fig. 4 is a view of a modified form of my device in which the lever connecting the sash to the counterbalaneing-weight is pivoted to a fixed support. Fig. 5 is an elevation of the lower part of a window-sash, showing a form of my invention in which the weight mechanism is attached through the medium of cords. Fig. 6 is a view similar to that shown in Fig. 5, illustrating the use of a spring in place of a weight for operating my device. Fig. 7 is a sectional elevation through the toothed rack and quadrant of the form of my device shown in Fig. 5, illustrating the application thereto of a second form of spring; and Fig. 8 is a sectional elevation on the line 8 8, Fig. 7.

In the preferred form of my invention, as illustrated in Figs. 1 and 2 of the above drawings, A is a window-sash of the form commonly used in railroad-cars, set in its frame so as to have a range of motion of about eighteen inches vertically. B is a lever, consisting of an elongated bar I), engaging the lower portion of the sash at one end and having at the other a quadrant 19, preferably toothed and in engagement with a rack G, suitably held to the supporting-framework.

To the extreme end of the lever is pivotally attached a weight D, and there is a pin I) placed so as to project laterally from the quadrant and fixed to the same at a point coincident with the center of the toothed arc of the quadrant. There is a slot 0 formed in the supporting-framework in which this pin moves, the latter serving to retain the lever B in position. The upper end I) of the lever is connected to the sash, as shown in the enlarged section illustrated in Fig. 2, it being seen that the lower part of the sash A has in it a horizontal groove or slot at, preferably lined with metal a. A pin 6 extends laterally from the said upper portion of the lever B and enters the groove a, being provided at its end with an antifriction-roller b fBeyond this point of attachment of the end I) of the lever B in the sash is a handle b whereby the device may be operated and the sash raised or lowered.

When it is desired to raise the windowsash, the handle 19 of the lever B is moved upwardly, thus raising the said sash as the pin b moves toward the opposite side thereof through the slot or groove 0.. Such action causes the toothed quadrant Z) of the lever B to roll on the rack C, the sash and its operating mechanism finally assuming the position indicated by dotted lines in Fig.1. From this it is seen that the lever B assumes a position to the extreme left-hand side of the sash not in any way interfering with or projecting across the opening left by the sash.

If desired, the device may be attached to the top instead of the bottom of the windowsash, as in the arrangement shown in Fig. 3. It is not absolutely essential that the quadrant b, with its corresponding rack, be provided with teeth, since the said teeth can be done away with without materially departing from my invention.

Should it not be required to have thelever B move bodily to one side when the window is raised, I may, if I desire, arrange the parts as shown in Fig. 4, in which the lever B is pivoted by a pin 11 to a support E, the weight of the sash being counterbalanced to a greater or less extent by the weight D, as before.

It is obvious that the slot 0 as such is not a necessity, since the pin b may extend ungaging with the slot parallel to the bottom of the sash, this latter is positively pulled down,

and the lever is moved from its elevated position to the position shown in full lines in said figure.

If it be desired, the connection between the toothed quadrant and the window-sash may be made through the medium of cords b, Fig. 5. s In such construction the said quadrant and rack are made relatively much larger than in the form of device illustrated in Figs. 1 and 3, and the cords b are connected to the formerat or near the center 19 from which the curved periphery is described, the weight D being preferably formed integral with the quadrant, as shown. The cords pass over the pulleys b fixed to the window-frame, one of them being connected directly to one of the lower corners of the sash and the other running down to the end of an arm a rigidly attached to the other corner of said sash. Under normal conditions the window is held down in its closed position by any suitable form of catch or latch, and upon this being released the weight D causes the quadrant b, to roll on the rack O, pulling upwardly through the cord b on the bar a and raising the sash.

Under certain conditions the quadrant and weight may be replaced bya form of pivoted lever B as shown in Fig. 6, which has a coiled spring 5 serving as the means for operatin g the window-sash. This spring is fixed to one arm of an L-shaped piece I)", whose other arm may be removably held to the framework in any desired manner.

If desired, the toothed quadrant shown in the figures may be formed with a groove 0 in its face, in which is held a bar or laminated spring 0, this being bent, as shown, at one end and entering a recess in the rack C, while at the other end it is held to said quadrant, the rack being also grooved on its toothed face, as at 0 for said spring, as shown in Figs. 7 and 8. It will be understood that this latter construction may be employed without the gear-teeth on rack'and quadrant, the smooth surface of the latter simply roll ing on the similarly-smooth surface of the rack.

I claim as my invention v1. The combination of a window-sash, a lever supported in a plane parallel to that of the sash and in sliding engagement therewith, a weight directly connected to the lever to balance the weight of the sash and means for supporting the lever, substantially as described.

2. The combination of a window-sash, alever in operative engagement therewith, a support havinga surface coacting with a surface on the lever and a weight connected to said lever, for balancing the weight of the sash, substantially as described.

3. The combination of a window-sash, a lever connected thereto, a support for the lever, a surface on said lever constructed to roll on the support when the sash is raised or lowered and a weight on the lever for balancing the weight of the sash, substantially as described.

4E. The combination of a Window-sash, a lever in sliding engagement with the same, said lever having a toothed segment and a weight, and a support having a toothed portion coacting with the segment on the lever, the said segment rolling on the support when the sash is operated, substantially as described.

5. The combination of a window-sash, a framework having a supporting-surface and a slot, a lever in engagement with the sash having a portion constructed to roll on the supporting-surface of the frame, a projection from the lever adapted to said slot, and a weight on said lever, substantially as described.

6. The combination of a window-sash, a framework having a supporting-surface and a slot, a lever in engagement with the sash having a curved portion constructed to roll on said supporting-surface, a projection from the lever at a point thereon coincident with the point from which its curved portion is described, the same being adapted to the slot and a weight on the lever, substantially as described.

7. The combination of a window-sash, a supporting-surface, a piece connected to the sash and movable upon said surface, and means attached to the movable piece for balancing the weight of the sash, substantially as described.

8. The combination of a window-sash, a lever connected thereto and provided with a support, said lever having a portion constructed to roll on said support when the sash is operated and means connected to the lever for counterbalancing the weight of the sash to any desired extent, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PAUL A. HOUGHTALING.
